Why each option

FortiGate offers multiple methods for sending One Time Passwords (OTPs) to users for Two-Factor Authentication, including dedicated hardware and software tokens, and email delivery.

AHardware FortiTokenCorrect

Hardware FortiToken devices are physical tokens that generate time-based OTPs which users enter for authentication.

BWeb Portal

A web portal is typically an interface for user login where an OTP might be entered, but it is not a method for FortiGate to *send* an OTP to the user.

CEmailCorrect

FortiGate can be configured to send OTPs to users' registered email addresses, allowing them to retrieve the code for authentication.

DUSB Token

While a USB token can be a form of hardware security key, FortiGate's proprietary OTP system primarily supports FortiToken hardware and software, not generic USB tokens for OTP generation.

ESoftware FortiToken (FortiToken mobile)Correct

Software FortiToken (FortiToken Mobile) is a mobile application that generates OTPs on a user's smartphone or tablet.
